The Marines that are fighting don't have the chance to hate OUR foreign policy. Theres is not to reason why, but to do and die. They don't ask question, they just do as they are told, could you? I don't know how easy it would be due to your prior service. The people that already served in the Marine Corps that are wanting to get back in are having a hard time. If they don't consider your prior service and you have a green card, it would be easy to enlist.
